I have spent the past week and a half attempting drive cycles to get my 98 to pass inspection. I have done about 2 drive cycles per day and put approximately 200 miles on the car this week alone. Originally I was getting a Small EVAP leak check engine and cleared the code about a week and a half ago. Since then I tightened up the gas cap thinking it was the cause. The check engine light hasn't come back but I am still running into issues.

I need 3 out of the 5 to pass but here is my issue
AIR-INC
EGR-INC
02 sensor- OK
02 sensor heater-OK
catalyst efficiency-INC

I can't get 1 more readiness monitor to pass so I can be done with this inspection. Besides going thru drive cycle listed what advise can you give? I have been cruising @ 55 for approximately 7 minutes per day and coasting to 20 mph without clutch or brakes and then accelerating again. I have been taking the car out on the highway late night to accomplish this. I feel like a Nascar driver with all the laps I've taken on the highway. Does anyone have any tips to get 1 more monitor listed above to show ready ?? I am running out of time to pass this inspection.

 

I had 5 monitors not ready on my 98Z,I needed to get a temp tag because I ran out of time. With the temp tag I did a GM drive cycle,nothing changed. Since the tag was 30 days I just started normal daily driving as I would normally use it. After 1 day 1 of the 5 became ready,every day another monitor became ready,after 5 days all 5 became ready.

 

Drive Cycles are also weather dependant. If it's not at least 65 degrees outside, you may have trouble getting them to set. IF your driving at night the weather temp outside could be your issue.

Air injection only runs at cold startup.

Catalyst efficiency usually sets on a long drive at 55-60mph steady for a few miles.

EGR is the same but it has to see very light pedal input. to much and it wont work.

 

So my evap finally set @ approx 300 miles worth of mixed city/highway driving. Worst part is so did my check engine light for a small evap leak. I got a temp inspection 10 day extension and bought a new gas cap being it did look a little worn. Here we go again lol
